Statement of Significance (as of designation - April 19, 1994):
The architectural heritage of Sag Harbor dates largely from the first half of the 19th century when it was a booming whaling town. Old Whaler's Church (1843-1844) was built with the support of wealthy ship owners, captains, and local businessmen, when Sag Harbor was at the height of its prosperity. One of the most important buildings in town, this church is also one of the most important buildings in the Egyptian Revival style to be found in the United States. Its battered walls and tall slanted windows are derived from ancient Egyptian temples, while Greek Revival motifs are employed along with cornice details that are adaptations of whaling implements. The architect was Minard Lafever.
